RADIATOR-AIR-VALVE PROTECTOR.

Application led January 26, 1918.

To all whom t may concern.'

Be it known that I, GEORGE RUDIsoH- HAUsER, a citizen of the UnitedStates, and a resident of the city of New York, (borough of Manhattan,in the county and State of New York, have invented a new and ImprovedRadiator Air Valve Protector, of which the following is a full, clear,and eX- act description.

M v invention relates to means for preventin'g unauthorized persons frommanipulating' the air valve of a radiator and thereby interfering withthe proper working of the heating system.

An object of the invention is tov provide a simple and inexpensivecontrivance which can be easily applied to a radiator air valve.

Another object of the invention is to provide a contrivance of the classdescribed which is applicable to a radiator air valve which has a top orbottom vent or both.

l/Vith the above and other objects in view, the nature of which willmore fully appear as the description proceeds, the invention consists inthe novel construction, combination and arrangement of parts as hereinfully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of a radiator air valve having a top air ventand which is provided with a protector embodying my invention, theprotector being shown in vertical section;

Fig. 2, an elevation of an air valve having a bottom and top ventprovided with a protector, shown in vertical cross section, and whichprotector prevents access to either vent of the valve; and

Fig. 3, an elevation of the protector as it would appear if a sectionwere taken on line 3 3, Fig. '2.

Referring to Fig. 1, 4 is a suitable tubular shell of a diametersulliciently large to receive therein a radiator air valve 5. Preferablythe diameter of the tubular shell is large enough to accommodate thewidest part of the valve, but this is not necessary. It may be madelarge enough to engage the part of the valve directly below the vent 6,particularly in cases where the valve has only a top vent as shown inFig. 1. The shell is suiiiciently long to present a material clearanceabove the vent 6. It has at l Specification of Letters Patent.

the shell 4 has a transverse socket 9 eXtendn ing transversely of theshell near the upper part of same. The shell has openings registeringwith the socket, one opening 10 being of a diameter equal to that of thesocket, while the other opening 11 is smaller so that the side of theshell presents a shoulder for the collar 12 of the set screw. The head13 of the screw is preferably of angular cross section so that a specialsocket wrench is necessary for manipulating said screw within thesocket. The screw has a thread ed opening in the radiator body 14whereby the shell can be secured to the radiator. A suitable spacer 15is provided between the shell and the radiator to maintain the shell inproper alinement with the radiator valve 5.

When the air valve 5 (see Fig. 2) has a top and bottom lvent 6 then, inadditionto the shell 4, a cover shell 16 is provided which is similar tothe shell 4 but slightly larger so that it may telescope over the shell4 (see Fig. 3). Since the cover shell must clear the stem 17 of the airvalve, it is provided with a longitudinal slot 18 which is open at theopen end of the cover shell 16. In view of the fact that the studsecuring the shells to the radiator body must be in vertical alinementwith the stem 17, the slot 18 is deviated from the vertical to provide abody portion outside the opening for the set screw in the cover shell16, thereby the set screw will lock the cover shell while it locks theshell 4 and thereby prevent the removal of either by an unauthorizedperson. It is self-evident that the cover shell has an opening 19 whichregisters with the opening 10 to give access to a socket wrench tomanipulate the set screw.

From the above description it will be seen that a radiator air valveequipped with a protector as described will prevent any unauthorizedperson from manipulating the valve of the vent 6 and thereby interferewith the proper operation of the heating system. It will also prevent anunauthorized person from detaching the radiator air valve.

I claim:
